Logical Execution Order of Query Clauses can implement the entire logic using a single query block?– it’s not always necessary, because Oracle can eliminate inline views during the query transformations. Moreover, in some cases additional inline views may help to improve the performance as it will be shown in the end of the chapter.作者: Nonconformist 時(shí)間: 2025-3-22 07:52
Turing Completenessinteresting to analyze whether it‘s Turing complete or not for the sake of completeness. Moreover, as will be shown in the next chapter "When PL/SQL Is Better Than Vanilla SQL," sometimes pure SQL is not the best way to get the result even if an algorithm can be easily implemented using it.作者: rheumatism 時(shí)間: 2025-3-22 11:00
Recursive Subquery Factoringve impact on the performance because the transformation engine doesn’t treat named queries in the same way as inline views. For example, on older versions Oracle could have merged an inline view but not the named query with exactly the same text.作者: 冷淡一切 時(shí)間: 2025-3-22 13:09

Row Pattern Matching: match_recognizeThis is required in many business areas, for example, security applications and fraud detection or financial applications and pricing analysis. Native pattern-matching capabilities in SQL help to avoid complex bespoke solutions on the client side or within the middle-tier application server and use easy-to-share SQL queries instead.作者: interpose 時(shí)間: 2025-3-23 17:05

Recursive Subquery Factoringe it did not allow us to define recursive subqueries and was mainly used to decompose the logic into named queries?– factor out subqueries and reference them by names in the main query.
